If you buy a sweatshirt from one of the gift shops, try it on! I just got a Jamaica one from the CN Gift Shop and a logo one from the CN Botique. They run about 2 sizes too small. I got two mediums and should have gotten X-larges. We washed them in cold water, so I don't think they shrank during washing.
The T-shirts run fine. In 4 visits starting in 2006, all the t-shirts (probably 10) have been correctly sized.
Newbie going to CN in May! How are the prices for t-shirts and sweatshirts? We have four kids to buy for! And I want to get them "lousy" t-shirts from Jamaica! lol Since they've been giving us a hard time about not taking them! lol
